BAR FOR THE MANUFACTURE OF SHOVEL--BLANKS.

SPECIFICATION forming part of Letters Patent No. 405,415, dated June 18,1889.

Application filed April 4, 1889. Serial No. 305,919- (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES J. JOHNSTON, a citizen of the United States,residing at Columbiana, in the county of Columbiana and State of Ohio,have invented certain new and useful Improvements in Bars for theManufacture of Shovel-Blanks; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to the art of making shovels, and has for itsobject the construction of a bar as a new article of manufacture for theproduction of double shovel-blanks.

The invent-ion will be hereinafter described, and particularly pointedout in the claim.

In the accompanying drawings, which form part of this specification,Figure 1 represents a plan view of my improved bar, and Fig. 2 aperspective view of a blank severed from. the bar.

Reference being had to the drawings and the letters thereon, A indicatesa bar of iron or steel having projections or tangs B B on the edgesthereof directly opposite each other for forming the handle-straps of ashovel, spade, or scoop when properly rolled or plated out. The distancebetween the centers (or line as) of the projections 13 B is about equalto the width of a finished shovel, spade, or scoop, and the bar issevered transversely midway between the projections, as on the dottedlines a a, to form blanks C for the manufacture of double shovel-blanks.

The bar may be produced by rolling or in any other suitable manner, andblanks after having been severed from the bar are rolled in thedirection of the projections B B to form handlestraps.

I11 the manufacture of double blanks with single handle-straps for usein making the Antrim shovel the tangs are not split; but in themanufacture of shovels with double handle-straps the projections aresplit. In reducing the blank between rolls the displacement of the metalis always in the line of the angle of force applied, and, as aconsequence, the metal of the projections will be sufficient to form ahandle strap or straps.

Having thus fully described my invention, what I claim, is

As an article of manufacture, a bar for making double shovel-blanks,said bar having projections on its edges opposite each other, and thedistance between the centers or lines x of said projections being aboutequal to the width of a shovel-blade, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES J. JOHNSTON.
